A sekrup bola adalah elemen mekanis yang biasa digunakan untuk mengirimkan gerakan dan kekuatan. Ini terdiri dari poros berulir dan kacang, dan bola digunakan untuk mentransmisikan gaya dan gerakan melalui benang di antara poros berulir dan kacang. Bola memainkan peran gaya transmisi, mengurangi gesekan dan gerakan samping, dan meningkatkan efisiensi dan presisi transmisi. Kriteria identifikasi sekrup bola dapat dijelaskan oleh aspek -aspek berikut. Yang pertama adalah pitch, yang menunjukkan jarak sekrup bola bergerak maju per rotasi. Pitch menentukan kecepatan dan sensitivitas sekrup bola, biasanya diekspresikan dalam milimeter/belokan atau inci/belokan.Yang kedua adalah kapasitas muatan. Kapasitas beban sekrup bola menggambarkan beban maksimum yang dapat ditahan, biasanya di newton (n) atau pound-force (LBF). Kapasitas beban secara langsung mempengaruhi ruang lingkup penggunaan dan penerapan sekrup bola. Lingkungan dan persyaratan kerja yang berbeda memerlukan pemilihan kapasitas beban yang sesuai. Yang ketiga adalah tingkat akurasi. Tingkat akurasi mengacu pada keakuratan pergerakan dan transmisi sekrup bola. Umumnya digunakan Tingkat akurasi termasuk C0, C3, C5, dll. Kelas akurasi menentukan akurasi penentuan posisi dan pengulangan sekrup bola, yang sangat penting untuk aplikasi yang membutuhkan kontrol posisi presisi tinggi. Selain itu, diameter, panjang, material, dll. Sekrup bola juga merupakan konten penting dalam deskripsi identifikasi. Diameter dan panjang mempengaruhi ukuran keseluruhan dan metode pemasangan sekrup bola, sedangkan bahan menentukan kekuatan dan daya tahan sekrup bola. Nanjing Shuntai Precision Ball Screw Pasangan distandarisasi menjadi 8 jenis kacang seperti yang ditunjukkan pada gambar. Selain itu, untuk memenuhi kebutuhan pelanggan, kami dapat membuat kacang non-standar dengan bentuk khusus (seperti persegi, persimpangan sumbu, dll.), Sifat khusus (seperti resistansi suhu tinggi, resistansi korosi, dll.) Dan format yang tidak konvensional (seperti ekstensi, beban berat). Jika Anda memiliki kebutuhan, silakan konsultasikan.

As a key transmission component for converting rotary to linear motion, ball screws have become the "heart" of high-end equipment such as precision instruments, CNC machine tools, and automated equipment, directly determining the operating accuracy and stability of the equipment, thanks to their three core advantages: "high precision, high efficiency, and high rigidity". Eight Key Points for Daily Maintenance Cleaning and Protection: Regularly clean the lead screw surface with a brush or compressed air to remove dust and chips, preventing impurities from entering the raceway; in harsh environments, install dust covers and protective sleeves. Scientific Lubrication: Select lubricant according to operating conditions, and replenish/change oil regularly according to operating time to ensure uniform lubrication of the raceway. Load Control: Strictly adhere to rated load requirements, avoiding instantaneous overload or impact loads to prevent lead screw deformation. Precise Installation: Ensure the lead screw is parallel and coaxial with the guide rail during installation, and tighten the bearings. Environmental Adaptability: Keep away from high temperature, high humidity, and corrosive environments. Take heat insulation, moisture-proof, and anti-corrosion measures when necessary. Regular Inspection: Establish an operation log, record changes in noise, temperature, and accuracy, and stop the machine for repair immediately if any abnormalities are found. Maintenance During Idle Time: When not in use for a long time, apply anti-rust oil and cover with a protective cover to prevent rust and dust accumulation. Synchronous Maintenance: Simultaneously check mating components (bearings, guide rails, drive motor) to ensure the stable and coordinated operation of the entire transmission system. Prevention and Inspection Techniques Visual Inspection: Inspect the lead screw surface for scratches, rust, and dents; check for intact and undamaged threads. Lubrication Check: Observe the even distribution of lubricant. If the color turns black or the viscosity decreases, replace it immediately. Smoothness Test: Manually rotate the lead screw or run it under no-load to check for any jamming or uneven resistance. Noise Identification: Listen for abnormal friction or impact sounds during operation, paying particular attention to the bearing area. Accuracy Inspection: Use a dial indicator and laser interferometer to check the positioning accuracy and repeatability, comparing them with standard values ​​to determine if the accuracy is satisfactory. Exceeding limits; Clearance Measurement: Use a feeler gauge or dial indicator to check the clearance between the lead screw and nut. If it exceeds the limit, the component needs to be replaced; Connection Tightness: Check the bolts of the bearing housing, coupling, and nut housing to prevent loosening that could cause vibration; Temperature Monitoring: Use a thermometer to check the temperature of the bearing and lead screw body after operation. If it exceeds 60℃, lubrication or installation problems need to be investigated; Cleanliness Assessment: Check for chips and oil accumulation around the lead screw and clean them promptly; Thread Flaw Detection: For lead screws in critical operating conditions, use magnetic particle testing or penetrant testing to check for hidden thread damage.
